Mario paid three bushels of rice for three boxes of wool at the market. what type of money did mario use for this exchange?

Mario did not use money to pay for the goods, but instead used the bartering system. This is where individuals agree to trade physical items or services in return for one of equal value. The bartering system is an ancient payment system, however may still be used when both parties are in agreement.

Iwould think a loan officer but i'm not sure
